IMPROVED CUTTING DEVICE FOR HARVESTERS.

Specfication forming part of Letters Patcnt No. l 5,334, dated July 15, 1856.

;L'o all whom 'it may concern:

Beit known that I, CARLOS W. GLOVER, of Roxbury, in the county of Litchficld and State of Connecticut, have inventcd a new and useful Improvement in the Sickles or Outting Deviees of Harvesting-Machines; and I do'hereby declare that the following is a full, clear, and exact description of the same, reference being had t-o the annexed drawings, making a part of this specication, in which- Figure l is a transverse section of my improvement, x w, Fig. 2, showing the plane of section. Fig. 2 is a. longitudinal section of the same, y y, Fig. 1, showing the plane of section. Fig. 3 is a horizontal section ot' the same, z z, Fig. 1, showing the plane of section.

Similar letters ot referenceindicate correspondiug parts in the several figures.

My invention consists in piacing a rocking V-shapcd or double cutter within each finger,

and over which cutters the ordinary sickle works, the parts being arranged and operating as will be hereinatter fully shown and described, whereby the sickle is made to cut much more effectually than those in present use, and without the danger of being clogged or choked by the grass or grain.

To enable those skilled in the art to fully understand and construct my invention, l will proceed to describe it.

A represents a finger-bar, to which fingers B are attached, and U represents a sickle having the usnal saw-shaped teeth, a, attached to a bar, D. The above parts are constructed in the usual way, and therefore do not require a minute description. A

Within each finger B there isplaced a rocking cutter, E. These cutters are of V form or shape, as shown clearly'in Fig. 2, and have the cutting-edges b b', one at each side of its npper part. The cutters E may be made of steel plate bent in the required form. The cutters E are fitted in grooves or recesses c, made in the lower parts of the usnal slots in the fin gers, and a suflicient space is allowed between the upper ends of the cutters E and thelower ed ges of the projecting lips or arms d of the fingers to receive the sickle-teeth a and allow them to work back and forth therein. (See Figs. 1 and 2.) The front ends of the cutters E, at their lower parts, have each a short projection, e, attached, and these projections fit in recesses f in the fingers. motion is given the sickle C in any proper manner, and as the teeth a of the sickle work back and forth over the cutters E the edges Z b' of said cutters will bear alternately against the cutting-edges of the teeth a. For instance, When the sickle is moving in the direction of the black arrow, Fig. 2, the cutting-edge b will i bear against the cutting-edge l of the teeth a. and when moving in the opposite direction, as indicated by the red arrow, the cuttingedge b' of the cutters E will bear against the cuttingedge 2 of the teeth a. The cutting-edges of the teeth a and cutters E act similar to a pair of shears, and as the cutters E rock or oscillate back and forth they are, by the action of the sickle G upon them, bound or pressed against the teeth a, s`o that the cutting-edges ot' the teeth and cutters will work snugly together and cut the grain or grass in a perfect and eX- peditious manner.

By the above improvement the sickle cannot become choked or clogged, as the grain or grass cannot pass between the cutting-edges ot' the teeth a and cutters E, owing to their close working, or in consequence of being at all times closely in contact.

Having thus described my invention, what I claim as new, and desire to secure by'Lctters Patent, is v The oscillating or rocking cutters E, placed within the fingers B, and used in connection with the sickle C, substantially as described,

for the purpose set forth.
